This unique seating option features a child-sized, anti-burst exercise ball covered with easy-to-clean 100 percent polyester mesh fabric. The chair provides the subtle bounce of a traditional exercise ball, but features a wide, sturdy four-leg base that keeps kids safely in place. Choose from three vibrant colors. Seat height is 17". Includes a pump for easy inflation as needed. Safco's Runtz Ball Chair is GREENGUARD certified and comes backed by a five-year warranty.
